%X The goal of this dissertation is mainly to search for glass hosts suitable for broadband fiber amplifiers, blue and green lasers. This research on spectral properties and crystallization stability of Er3 +-doped heavy metal oxyfluoride glasses and upconversion luminescence of rare earth-doped heavy metal oxyhalide glasses lays a foundation for the potential use of the broadband Er3+ -doped fiber amplifier, blue and green lasers. The results showed that the bandwidth properties and gain performance of Er3+ -doped silicate and germanate glasses increased due to addition of heavy metal lead fluoride. In addition,upconversion blue emission in Er3 +/Yb3+ -codoped and Er3+ -doped silicate glasses was observed for the first time, upconversion luminescence intensity of Er3+ -doped germanate and tellurite glasses increased with increasing of heavy metal lead fluoride, and upconversion blue, green and red emissions,corresponding to the 2H9/2 →4I15/2 , 2H11/2 →4I15/2 , 4S3/2 →4I15/2 , and 4F9/2 →4I15/2 transitions of Er3+,respectively, were simultaneously observed at room temperature. Mixed lead halide modified Tm3+/Yb3+-codoped tellurite glasses are improving crystallization stability of host glasses and upconversion luminescence, and upconversion blue and red emission corresponding to the 1G4→3H6 and 1 G4 →3H4transitions of Tm3+ , respectively, were simultaneously observed at room temperature. It was discovered for the first time that OH group absorption had important effects on upconversion emission of Er3 + and Tm3+ doped tellurite glasses.
